Highway Speed Problem
Heres the issue. I about have my carb dialed in with no bog anywhere part throttle. However if I put it to the floor it will be fine for a few seconds then miss/bog/hesitate? 65 on the highway and put it to the floor and the speed increase stops and just stays there until you let up a little. This happens at any speed. Its a 283/th350. Qjet, HEI. initial timing is 14btdc(at 5500 ft and seemed to help alleviate some issues) total I'm unsure of until I get my timing tape put on(waiting until I piston stop find TTDC). This didn't happen before carb rebuild.

Re: Highway Speed Problem
Sounds to me it's something with your carb. My old mustang use to do that with the Webber that was on it
